TWO-WAY HINGE.

Application filed December 6, 1926. Serial No. 152,972.

The present invention relates to hinges,

and more particularly to thetype of hinge adapted to connect panels or members together and permit the same to swing into overlapping relation or through 180 degrees.

An object of the present invention is to provide a hinge of this character, which is of relatively simple and durable construction, which may be made from sheet metal at small cost, which may be mounted upon a screen or upon other relatively fol-ding or hinging sections to effectively connect the same and permit of the free movements thereof, and which at the same time provides a hinge which may be embedded in narrow slots of the connected members or be mounted fiat against the opposite ends of the same.

Another object of this invention is to provide a hinge, which has intergeared parts, so that when two or more of the hinges are used between the connected members, the hinges are caused to move simultaneously and equally and the members are inter-braced through the hinge upon each other.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claim appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a perspective view of applicants hinge as applied to a plurality of screen panels.

Figure 2 is a fragmentary enlarged side elevation of one of the hinge connections of the screen. 1

Figure 3 is a detail top plan view.

Figure 4% is a. bottom plan view of the same.

Figure 5 is an end view thereof.

Figure 6 is a transverse section taken through the hinge on the line 1313'of Figure 2 showing the prongs bent inwardly, and

Figure 7 is a longitudinal section of the hinge taken on the line 14-1 1 of Figure 3.

Referring now to the drawing, the hinge comprises a pair of toothed plates 20 and 21 which are intergeared and provided with a connecting link 22. The plates 20 and 21 are provided with central openings the material from which is punched upwardly or to one side of the plates 20 and 21 to form rivets 23 integral with the plates and which are spread or turned over against the walls of: the openings in the link 22, the walls of the FEQ.

22 and permit of the free turning ofthe plates on the link. The plates 20 and 21 are provided at their inner ends with pairs of attaching ears 24 adapted to be bent down against the opposite sides of the stile or other member upon which the hinge is mounted, and the cars 24 may be provided with prongs 25 which extend at a suitable angle to the cars 24 so that the prongs may be driven into the opposite sides of the stile or support for anchoring the ears and the toothed plates 20 and 21 to the supports. As shown in Figures 4, 6 and 7 the prongs 25 are preferably bent at the inclination toward the inner or lower side of the adjacent attaching plate, so that (if) i the prongs when driven into the stile will i have a slightly upward inclination and thus resist any pressuresv or. strains tending to dislodge the geared plates.

The advantage of this type of hinge is that it'presents but two thicknesses of material and the rivets are not only integral with the toothed plates and can be stamped in the manufacture thereof, but the rivets lie within the openings of thelink and, thus do not project from the surface of the link.

As shown in Figures 1 and 2 this type of hinge may be inserted in a relatively narrow slot 26 formed in the stile 27 of a screen door or the like and may be easily secured or fixed in place without the use of screws or the like.

It is apparent then that when the hinge is mounted in the slots as above described itis practically concealed.

It is obvious that various changes and modifications may be made in the details of construction and design-of the above specithereof and with the material from the open-.

ing struck from one side of the plate to provide a rivet, said plate also having a pair of oppositely extending ears at its inner end, said ears adapted to be bent over against the opposite sides of a stile for attachment thereto for holding the geared plates in position, and 2i link connecting said intefgeai'edplates together and having openings in opposite ends adapted to receive said rivets of the 7 SAMUEL c.
